corrected handling of `constrains` elements

removed non-BSD compatible option from cp

Geoff's formatter now needs closed formulas

Using type real does not require a separate logic now.

merged

tuned text about "value" and added note on comments.

simplified command status: interpret stacked markup on demand;

event_bus.scala rather belongs to system plumbing;

some derived operations on Text.Range;

specific types Text.Offset and Text.Range; minor tuning;

moved Text_Edit to Text.Edit; tuned;

moved History/Snapshot to document.scala;

renamed raw_results to raw_protocol;

rename "unit" to "atom", to avoid confusion with the unit type;

document commands: maintain transition as future (wrt. potentially slow Outer_Syntax.prepare_command), refrain from second Toplevel.put_id;

use Synchronized.var and prevent global CRITICAL sections in this hot spot;

renamed create_id to new_id;

more explicit / functional ML version of document model; tuned;

renamed class Document to Document.Version etc.; renamed Change.prev to Change.previous, and Change.document to Change.current; tuned;

fixed Isabelle/Scala build (cf. f3220ef79d51);

Snapshot.state: fall back on Command.empty_state -- looked-up command might be unavailable due to editing divergence;

more basic Markup.parse_int/print_int (using signed_string_of_int) (ML); added convenient Markup.Int/Long objects (Scala); simplified "assign" message format -- explicit version id; misc tuning and simplification;

Keyword.status: always suppress position;

moved isar_document.ML/scala to Pure/System/ -- side-by-side with isar.ML;

remove reinit operation alltogether

avoid arcane Local_Theory.reinit entirely

more convenient split of class modules: class and class_declaration

stripped signature

explicit accessed to structure Class_Target

tuned lowercase

moved Document.text_edits to Thy_Syntax;

tuned;

added Isabelle_Process.input_bytes, which avoids the somewhat slow Standard_System.string_bytes (just in case someone wants to stream raw data at 250MB/s);

do not buffer fifo streams here -- done in Isabelle_Process; removed misleading comments -- blocking on open is not reliable on non-standard systems (Cygwin);

explicit Document.State value, instead of individual state variables in Session, Command, Document; Session.snapshot: pure value based on Document.State; Document.edit_texts: no treatment of state assignment here;

edit_document: more precise status position;

added get_after convenience;

more basic notion of unparsed input;

simplified/clarified Change: transition prev --edits--> result, based on futures; Session.history: plain List instead of somewhat indirect Change.ancestors; tuned;

moved snapshot to Session (cf. 96b22dfeb56a);

Change: eliminated id, which is merely the resulting document id and is only required in joined state anyway; Document.edit_text: create new document id here;

clarified "state" (accumulated data) vs. "exec" (execution that produces data); generic type Document.id (ML) / Document.ID;

misc tuning and simplification;

specific command state;

specific Session.Commands_Changed;

consider snapshot as service of Session, not Document.Change;

tuned scope;

Document.print_id;

consider command state as part of Snapshot, not Document;

represent document ids by (long) int, to benefit from the somewhat faster Inttab in ML (LinearSet in Scala is invariably indexed by native object ids);

Named_Target;

modernized specifications; tuned headers;

spelling;

merged

renamed Theory_Target to the more appropriate Named_Target

discontinue old implementation of `foundation`

moved instantiation target formally to class_target.ML

moved overloading target formally to overloading.ML

moved theory-level target operation fragements to Generic_Target; adjusted bootstrap order

merged

whitespace tuning

remove overloading and instantiation from data slot

removed obsolete Toplevel.enter_proof_body;

standardized pretty printing of consts (e.g. see find_theorems, print_theory);

misc tuning and simplification;

simplified/unified command setup;

removed obsolete Proof.get_thmss_cmd (cf. Attrib.eval_thms);

prefer plain Attrib.eval_thmss -- also means the assert_forward of Proof.get_thmss_cmd is skipped, leading to uniform (albeit odd) behaviour concerning forward chaining; tuned;

prefer plain Attrib.eval_thms with plain Proof.context instead of Proof.state;

tuned eval_thms (cf. note etc. in proof.ML);

use Pretty.enum convenience;

tuned whitespace;

more precise and more maintainable dependencies;

merged, resolving conflict in src/Pure/IsaMakefile concerning General/xml_data.ML;

* -> prod

added .ML extension

avoid old unnamed infix
